Her tour is coming up
– but Britney Spears
is still spending plenty of family time. The pop star took sons Preston and Jayden to visit the Tommy Hilfiger Prep World Pop Up House store at The Grove
in West Hollywood for a day of shopping. Joining them: Spears's dad, Jamie, and her assistant. Britney spent more than an hour browsing and trying out clothes (including a blue seersucker blazer and high-heeled navy boat shoes) while her boys sat in chairs, laughing and playing games.
